The present invention relates to improvements in rail guided vehicles and particularly to railguided vehicles having at least one group of axles consisting of two axles. Rail guided vehicles are already known comprising two bogies each containing a group of two axles, each bogie being linked to the frame carrying the vehicle body and the two bogies being connected to each other in such a manner that the axles are angularly adjusted to the curves. Vehicles havingv supporting frames on which the vehicle body is supported at central points, the bogies each having a pair of axles and each axle having an axle frame pivotally supporting its axles, and the axle frames being articulately connected together and angularly controlled by the position of the Vehicle body relative thereto are also known. This previously known lconstruction was intended for the purpose of adjusting the axles to the `curve of the track so as to avoid hunting and other undesirable action. This construction has been found to have the very undesirable action of beingY affected by lateral movements of the bodyrframe relative to the bogie frame and axle frame such as body swaying or lurching whereby the axles were forcibly brought to improper angular position, and further undesired actions and reactions were set up.

The present invention has for an object to iml prove the guiding of the axles of a vehicle supported in the above described manner in such a way that relative movement of the vehicle body laterally does not affect the adjustment of the axles, whereby hunting and other undesired actions of the axles are eliminated.

In the accompanying drawing illustrating the invention:-

Fig. 1 shows in a plan view a construction of a bogie having two axles;

Fig. 1a is a side sectional view illustrating the connection between the body and a car axle frame control mechanism. y

Fig. 2 shows a detail of Fig. 1 in elevation.

Fig. 3 shows on a larger scale and in a vertical section the connection point of the axle frames, and

Fig. 4 shows a detail of Fig. 3 in a plan view.

Referring now to the drawing in the constructional example illustrated in Fig. 1 K denotes the body of the rail-guided vehicle, which is provided in this case with two symmetrically arranged similar groups of axles built as bogies of the same type. Only one of the bogies is shown in Fig. 1 as the latterl shows one Vend portion of the vehicle only, the other end portion is identical. Every bogie D is provided with a frame I on which the body K is supported by the main pivot pin 2. On the bogie frame the two vertical pivot pins 3 and 4 are arranged by means of which the bogie frame rests on the axle frames 5 and 6 and about which the axle frames swing. The two axle frames are connected together at 'l in an articulated manner which permits of longitudinal displacement. Laterally of the longitudinal axis of the body K and outside ofthe main pin 2 the guide point 8 formed by apin is arranged and cooperates with the outer axle frame 5. In the axle frames 5 and 5 the axles 9 and' I0 are mounted. The aforedescribed example illustrated in Fig. 1 is a bogie for a trailer vehicle having the same axle pressures on both axles.V

One arm Ila of a bell-crank lever, turnably mounted in the longitudinal axis of the bogie frame on a cross member d of the'bogie frame D, cooperates with the pin l, whilst the other arm Hb of said lever extends at right angles to the arm lla towards'the side member of'the` bogie frame. The free end of the arm Hb is connected by a link l2 to the guide pin 8 of the Vehicle body, which guide pin is arranged laterally of the main turning axis of the bogie.

In the above described arrangement the lateral oscillations of the vehicle which unavoidably occur when the vehicle runs overa straight track owing to the play of the springs cause a swinging motion of the link I2 about the lever arm Hb and only a turning motion of the vehicle body in a curve causes a longitudinal movement of the link l2 and thereby a turning 0f the bell crank lever Il which positively causes the proper angular adjustment of the axle frames 5 and 6.

In Fig. 3 the construction of the connecting point of the two axle frames is illustrated. At the inner end of the frame 5 a casing 5a of a rectangular shape in a plan view is provided which is embraced by a fork 'shaped part 6a of the other axle frame 6 in which the pivot pin 'l is located, the elasticity of the rubber permitting the desired longitudinal displacement. In the casing 5a two rubber blocks I3 of rectangular prismatic shape are housed which hold the pin l by bearing bushes la. The end of the bell crank lever arm Ha, is also shaped as a rectangular casing IIb in which a similar rubber block I3 is inserted. In a similar manner an elastic connection between the axle frame on the one hand and the bell crank l'ever Il on the other hand is provided, in Fig. 2 only the pin f2.VA
